FIELD OF THE INVENTION

The present invention relates to beta and gamma-amino isoquinoline amidecompounds and substituted benzamide compounds that affect the functionof kinases in a cell and that are useful as therapeutic agents or withtherapeutic agents. In particular, these compounds are useful in thetreatment of eye diseases such as glaucoma, for the treatment ofcardiovascular diseases, and for diseases characterized by abnormalgrowth, such as cancers.

BACKGROUND

A variety of hormones, neurotransmitters and biologically activesubstances control, regulate or adjust the functions of living bodiesvia specific receptors located in cell membranes. Many of thesereceptors mediate the transmission of intracellular signals byactivating guanine nucleotide-binding proteins (G proteins) to which thereceptor is coupled. Such receptors are generically referred to asG-protein coupled receptors (GPCRs) and include, among others,α-adrenergic receptors, β-adrenergic receptors, opioid receptors,cannabinoid receptors and prostaglandin receptors. The biologicaleffects of activating these receptors is not direct but is mediated by ahost of intracellular proteins. The importance of these secondaryproteins has only recently been recognized and investigated asintervention points in disease states. One of the most important classesof these downstream effectors is the “kinase” class.

The various kinases thus play important roles in the regulation ofvarious physiological functions. For example, kinases have beenimplicated in a number of disease states, including, but not limited to:cardiac indications such as angina pectoris, essential hypertension,myocardial infarction, supraventricular and ventricular arrhythmias,congestive heart failure, atherosclerosis, renal failure, diabetes,respiratory indications such as asthma, chronic bronchitis,bronchospasm, emphysema, airway obstruction, upper respiratoryindications such as rhinitis, seasonal allergies, inflammatory disease,inflammation in response to injury, rheumatoid arthritis. The importanceof p38 MAPK inhibitors in particular as new drugs for rheumatoidarthritis is reflected by the large number of compounds that has beendeveloped over the last years (J. Westra and P. C. Limburg Mini-Reviewsin Medicinal Chemistry Volume 6, Number 8, August 2006). Otherconditions include chronic inflammatory bowel disease, glaucoma,hypergastrinemia, gastrointestinal indications such as acid/pepticdisorder, erosive esophagitis, gastrointestinal hypersecretion,mastocytosis, gastrointestinal reflux, peptic ulcer, Zollinger-Ellisonsyndrome, pain, obesity, bulimia nervosa, depression,obsessive-compulsive disorder, organ malformations (e.g., cardiacmalformations), neurodegenerative diseases such as Parkinson's Diseaseand Alzheimer's Disease, multiple sclerosis, Epstein-Barr infection andcancer (Nature Reviews Drug Discovery 2002, 1: 493-502). In otherdisease states, the role of kinases is only now becoming clear. Theretina is a complex tissue composed of multiple interconnected celllayers, highly specialized for transforming light and color intoelectrical signals that are perceived by the brain. Damage or death ofthe primary light-sensing cells, the photoreceptors, results indevastating effects on vision. Despite the identification of numerousmutations that cause inherited retinal degenerations, the cellular andmolecular mechanisms leading from the primary mutations to photoreceptorapoptosis are not well understood, but may involve the wnt pathway (A SHackam “The Wnt Signaling Pathway in Retinal Degeneration” IUBMB LifeVolume 57, Number 6/June 2005).

The success of the tyrosine-kinase inhibitor STI571 (Gleevec) in thetreatment of chronic myelogenous leukaemia (Nature Reviews DrugDiscovery 2003, 2: 296-313) has spurred considerable efforts to developother kinase inhibitors for the treatment of a wide range of othercancers (Nature Reviews Cancer 2003, 3: 650-665). The balance betweenthe initiation and the inactivation of intracellular signals determinesthe intensity and duration of the response of the receptors to stimulisuch as agonists. When desensitization occurs, the mediation orregulation of the physiological function mediated or regulated by the Gproteins to which the receptors are coupled is reduced or prevented. Forexample, when agonists are administered to treat a disease or conditionby activation of certain receptors, the receptors relatively quicklybecome desensitized from the action of the GRKs such that agonistadministration may no longer result in therapeutic activation of theappropriate receptors. At that point, administration of the agonist nolonger enables sufficient or effective control of or influence on thedisease or condition intended to be treated.

In view of the role that kinases have in many disease states, there isan urgent and continuing need for small molecule ligands which inhibitor modulate the activity of kinases. Without wishing to be bound bytheory, it is thought that modulation of the activity of kinases by thecompounds of the present invention is responsible for their beneficialeffects.

An effective amount of a compound according to the present inventionwill vary with the particular condition being treated, the age andphysical condition of the patient being treated, the severity of thecondition, the duration of treatment, the nature of concurrent therapy,the route of administration, the particular pharmaceutically-acceptablecarrier utilized, and like factors within the knowledge and expertise ofthe attending physician. For example, an effective amount of thecompounds of the present invention for systemic administration is fromabout 0.01 to about 1000 μg/kg body weight, preferably from about 0.1 toabout 100 μg/kg per body weight, most preferably form about 1 to about50 μg/kg body weight per day. The transdermal dosages will be designedto attain similar serum or plasma levels, based upon techniques known tothose skilled in the art of pharmacokinetics and transdermalformulations. Plasma levels for systemic administration are expected tobe in the range of 0.01 to 100 ng/mL, more preferably from 0.05 to 50ng/mL and most preferably from 0.1 to 10 ng/mL. While these dosages arebased upon a daily administration rate, the compounds of the presentinvention may also be administered at other intervals, such as twice perday, twice weekly, once weekly, or once a month. One of ordinary skillin the art would be able to calculate suitable effective amounts forother intervals of administration.

The compounds of the present invention are useful in a method ofreducing or decreasing intraocular pressure. The compounds of thepresent invention may be administered to a subject in need of treatmentin an amount effective to reduce intraocular pressure. Thus, thesecompounds are useful in the treatment of glaucoma. The preferred routeof administration for treating glaucoma is topically.

The exact amounts of each component in the topical composition depend onvarious factors. The amount of component A added to the topicalcomposition is dependent on the IC₅₀ of component A, typically expressedin nanomolar (nM) units. For example, if the IC₅₀ of the medicament is 1nM, the amount of component A will be from about 0.001 to about 0.3%. Ifthe IC₅₀ of the medicament is 10 nM, the amount of component A) will befrom about 0.01 to about 1%. If the IC₅₀ of the medicament is 100 nM,the amount of component A will be from about 0.1 to about 10%. If theIC₅₀ of the medicament is 1000 nM, the amount of component A will be 1to 100%, preferably 5% to 50%. If the amount of component A is outsidethe ranges specified above (i.e., lower), efficacy of the treatment maybe reduced. One skilled in the art understands how to calculate andunderstand an IC₅₀. The remainder of the composition, up to 100%, iscomponent B.

The amount of the carrier employed in conjunction with component A issufficient to provide a practical quantity of composition foradministration per unit dose of the medicament.

Unless otherwise noted, HPLC purification, when appropriate, wasperformed by redissolving the compound in a small volume of DMSO andfiltering through a 0.45 micron (nylon disc) syringe filter. Thesolution was then purified using, for example, a 50 mm Varian DynamaxHPLC 21.4 mm Microsorb Guard-8 C₈ column. A typical initial elutingmixture of 40-80% MeOH:H₂O was selected as appropriate for the targetcompound. This initial gradient was maintained for 0.5 minutes thenincreased to 100% MeOH:0% H₂O over 5 minutes. 100% MeOH was maintainedfor 2 more minutes before re-equilibration back to the initial startinggradient. A typical total run time was 8 minutes. The resultingfractions were analyzed, combined as appropriate, and then evaporated toprovide purified material.

All spectra were determined inthe solvents indicated. Although chemical shifts are reported in ppmdownfield of tetramethylsilane, they are referenced to the residualproton peak of the respective solvent peak for ¹H NMR. Interprotoncoupling constants are reported in Hertz (Hz).

Analytical LCMS spectra were obtained using a Waters ZQ MS ESIinstrument with an Alliance 2695 HPLC and a 2487 dual wavelength UVdetector. Spectra were analyzed at 254 and 230 nm. Samples were passedthrough a Waters Symmetry C18 4.6×75 mm 3.5μ column with or without aguard column (3.9×20 mm 5μ. Gradients were run with mobile phase A: 0.1%formic acid in H₂O and mobile phase B: ACN with a flow rate of 0.8mL/min. Two gradients will illustrate:
